SimpleCov::Configuration#add_filter

Add a filter to the processing chain.
There are three ways to define a filter:

* as a String that will then be matched against all source files' file paths,
  SimpleCov.add_filter 'app/models' # will reject all your models
* as a block which will be passed the source file in question and should either
  return a true or false value, depending on whether the file should be removed
  SimpleCov.add_filter do |src_file|
    File.basename(src_file.filename) == 'environment.rb'
  end # Will exclude environment.rb files from the results
* as an instance of a subclass of SimpleCov::Filter. See the documentation there
  on how to define your own filter classes
